Buick has announced a new engine for its LaCrosse range, featuring more technology and ultimately more power. The new direct injection 3.6-litre unit is now upgraded with a new head design and larger diameter intake valves among others. And there’s more power for the taking.
The new V6 is a total of 9.3kg lighter now, which is obviously very beneficial as far as performance is concerned. Not only that but maximum power is now 303 bhp (or 226kW), bringing it line with similar-sized V6s from Europe.
“Thanks to increased use of lightweight components and other enhancements,” said Doug Osterhoff, LaCrosse product marketing manager, “the new 3.6L V-6 offers 2012 LaCrosse buyers improved acceleration with no hit to fuel efficiency.”
